Answer:

1. r+s²=49

2. pq²=24

3. -4xy-6x²+2x²y-6y= -54

Step-by-step explanation:

1. r+s²=0+7²=49

2. pq²=(6)(2)²=6(4)=24

3. -4xy-6x²+2x²y-6y= -4(3)(2)-6(3)²+2(3)²(2)-6(2)

                                = -24-6(9)+2(9)(2)-12

                                = -24-54+36-12

                                = -78+36-12

                                = -42-12

                                = -54

Answer:

{(-2, -7), (-1, -5), (0, -3), (1, -1), (2, 1)}

Step-by-step explanation:

Consider an element in the set we want to achieve. This element can be written as the ordered pair (x, y), where x comes from the set {-2, -1, 0, 1, 2} and given some value of x, we can find y (with the formula y = 2 * x - 3).

So to begin finding the set of all pairs in the resulting set, we first begin by listing out all values of x in each pair:

(-2, y)

(-1, y)

(0, y)

(1, y)

(2, y)

Now to find y, we use the formula y = 2 * x - 3, and we get

(-2, 2 * (-2) - 3)

(-1, 2 * (-1) - 3)

(0, 2 * (0) - 3)

(1, 2 * (1) - 3)

(2, 2 * (2) - 3)

which simplifies to

(-2, -7)

(-1, -5)

(0, -3)

(1, -1)

(2, 1)

Find two numbers whose sum<br> is 37 and difference is 9.
JulijaS [17]

Answer:

23 and 14

Step-by-step explanation:

The sum of x and y is 37. In other words, x plus y equals 37 and can be written as equation A:

x + y = 37

The difference between x and y is 9. In other words, x minus y equals 9 and can be written as equation B:

x - y = 9

Now solve equation B for x to get the revised equation B:

x - y = 9

x = 9 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 37

9 + y + y = 37

9 + 2y = 37

2y = 28

y = 14

Now we know y is 14. Which means that we can substitute y for 14 in equation A and solve for x:

x + y = 37

x + 14 = 37

X = 23

Summary: The sum of two numbers is 37 and their difference is 9. What are the two numbers? Answer: 23 and 14 as proven here:

Sum: 23 + 14 = 37

Difference: 23 - 14 = 9

Kendrick’s bill for lunch was $24.50. He left the server an 18% tip. What is the total amount that Kendrick paid for lunch inclu
Mice21 [21]

Answer:

$28.91

Step-by-step explanation:

The first step is to calculate the amount of the tip. You multiply the price (24.50) by the tip amount (18% or 0.18). The product is 4.41. Then, you add the tip to the bill. 24.50+4.41=28.91.
